why is the Skoda Octavia's engine light flashing?

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface and the engine is off.
• Gather necessary tools and parts.

2. Retrieve and Analyze Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port.
• Turn the ignition to the "ON" position without starting the engine.
• Retrieve and record any error codes displayed.

3. Inspect Ignition System

• Remove the engine cover if necessary.
• Disconnect the spark plug wires and remove the spark plugs using a spark plug socket.
• Inspect each spark plug for excessive wear or fouling. Replace if necessary.
• Test ignition coils with a multimeter to ensure they are functioning correctly, replacing any faulty coils.

4. Check Fuel System

• Use a fuel pressure gauge to measure fuel pressure at the fuel rail.
• If pressure is low, inspect the fuel filter and fuel pump for clogs or failures.
• Replace the fuel filter if it hasn’t been changed according to the service schedule.

5. Inspect Intake and Exhaust

• Check for vacuum leaks around the intake manifold and throttle body; use a smoke machine if available.
• Inspect the air filter and replace if clogged.
• Examine the exhaust system for blockages, especially in the catalytic converter.
